Hitoshi Okamoto

All filings by Hitoshi Okamoto on record concern 株式会社ヤマナカ. We count 5 filings; the first trade dates from 25 March 2024 and the latest from 23 October 2026.

The open-market record is one-sided, with 3 purchases worth €123k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

A typical purchase (the median) is worth €40k. No cluster: in 3 purchases, no other insider of the company bought within 30 days.

On 28 October 2026 came the latest disclosure, a transaction in 株式会社ヤマナカ. The clock since the last published purchase (27 May 2024) now reads 895 days. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 5 days. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
